Abstract (en)
[origin: EP0343486A2] The present invention provides a novel process for manufacturing N-(polyoxyalkyl)-N-(alkyl) amines. The process is characterized by reacting a polyetheramine in which the amine groups are predominantly primary in character with a low molecular weight, sterically hindered alcohol in the presence of an appropriate catalyst, such as nickel using specific reaction conditions.
